Well I've tried both of the 24 by 16 division routines on the techref page and I couldn't get successful (or consistent) results with either. I put the same inputs into both routines and both gave different and incorrect outputs. So I opted to try looking at appnotes. That's just a mess. I can't decypher all those include files they have and the syntax for calling division routines in the source code zips....but I did recognize some variables AARG and BARG from one of the techref routines...so I assume it was built from that theory, but I can't make it happen. Does anyone know how to get a working division?
